PAD-FEEDING MEANS Application filed May 1,

This invention relates to a pad feeding means, which is associated' withA a stitching mechanism forv attaching the calendar pad withv a cord to the. calendar back.

l The invention includes means for feeding the calendar pads individually from the compartment in which a supply of pads is held. The stitching mechanism illustrated is of the ordinary" construction and is prolovid'ed with means to receive ai comparatively good sizedY calendar back, this necessitates the placing of the compartment of the supply of calendar' pads atY some distance from the stitching head. Thus, it is necessary to provide means for carrying the pads from the compartment to the point where they are to be stitchedl to the back;

A furtherA object of the invention is to provide means for feeding the calendar pads 2 from the supply compartment into a carrieig which is adapted to bring the pad ad- `iacent the position where it is to be stitched tothe back, at which point the pad is held stationary momentarily while the preceding pad is being stitchedV to the back. A second feeding means takes theA pad from the carrier and positions it under the calendar back in readiness to be stitched theretoby the stitching head;

fn the drawings forming a part of this specification Figure 1 is a side elevation of a portion of a stitching head illustrating the invention attached? thereto. s

Figure 2 is a plan view of the stitching headV and the calendar pad feeding mechani'sm.

Figure 3 is an enlarged detail of a portion ofthepad holding compartment and feeding mechanism associated therewith.

Figure l is a similarview tfoAFigure 3 with the parts in a different position.

Figure 5 is an enlarged detail of the second feeding means associated with the pad carrier.

In the drawings the stitcher head A is of ordinary construction and is supported by the arm 10, which extends to the back of Jthe machine where the main drive shaft 11 is 50 journaled, which operates the mechanism of the stitching head in the ordinary well known manner.

The stitching head A is positioned above the table 12 upon which the calendar backs 13, only a portion of which is illustrated in dotted outline in Figure 1, are placed and held iny position to receive a monthly calendar pad which is adapted to be stitched thereto.

The stitching machine illustrated in the drawings is provided with piercing needles 14 beneath the stitching head A and table 12 and is of the type adapted to stitch a cord or other flexible. material through the calendar back and pad and to tie the cord in av knot to attach the monthly pad tothe calendar back. This cord 15 is threaded through the stitching head A in the ordinary well known manner and is supplied from the. spool 16.

The calendar monthly pads 17 are'held. in the compartment B at a slightly inclined angle at the rear of the arm 10. The compartment B' is attached to the bracket a-rms 18.

The pad feeding finger 19V is positioned at the bottom of the compartment B andv is operated by the lever arms 2O and 21 to force the monthly pads 17 individually out of the opening 22 at the forward loweredge of the compartment. The arm 21- is pivoted at 23 to the sprocket wheel 24.- which is attached to the main operating shaft 11. At each revolution of the sha-ft 11 theV finger 19 is operated to eject a pad from the compartment B. f

The carrier composed of the tape belts 25 and 2,6 is positioned directly in front of the opening 22. and extends to the stitching table 12. rlhese beltsl 25 and 26' are operated by the. sprocket chain 27 and the intermeshing Vgears 28. During the operation of the mais also pivoted at 23 with the sprocket wheel 24.

In the operation of the stitching machine the fingers 19 and 29 operate in unison so that while a pad resting on the finger 29 is fed into the stitching position, another pad is fed from the compartment B to the carrier belts 25 and 26, and by the time the pad travels from the compartment B to the finger 29, the finger 29 is in receiving position.

Heretofore in the use of this style of stitching machine it was necessary to place the pads individually in position to be stitched to the calendar bacli. This was very unsatisfactory because it tool; a longer time and it was difficult to always have the calendar baci: and pad in the correct position in relation to each other, particularly for the reason that the pad is positioned below the calendar baci: and is not visible while being stitched. rllhis invention eliminates these undesirable features and increases the efficiency of the stitching machine to such an extent that a'much greater number of calendars can be stitched with absolute assurance of having the monthly pad in proper position in relation to the back.

Upon the lower portion in Figure 2 of the drawings elements 60 are shown which maintain the calendar back in raised position so that the pad can be inserted directly under the calendar back.

Figure 3 illustrates a portion of the compartment B with the individual pads 1? resting in position to be fed out of the opening 2Q and clearly illustrates the feeding linger 19. In this way the finger 19 is in backward position ready to engage the lower nost pad 17 and eject it from the compartment into the carrying belts 25 and 26.

Figure 4 illustrates the finger 19 in the position it assumes while feeding the pad 1T into the carrier belts 25 and Q6.

Figure 5 is an enlarged detail illustrating the feeding finger 29 in position to engage the pad 17 and to force it beneath the guard 33, below the calendar back 13, which is clearly illustrated in position on the stitching end tie table 1Q.

The drawings illustrate a particular form of our invention, but it is obvious that the same can be varied in design to perform the same functions so as to come within the scope of the following claims.

IVe claim:

1. In a device of the class described, including a stitching head, a stitching table, calendar monthly pad holding compartment, a feeding finger associated therewith, a second feeding finger associated with said table and pad carrier means interposed between the pad holding compartment and said second feeding finger whereby pads are antomatically fed individually from the compartment to the stitching table in position to be stitched to a calendar back.

2. In an article of manufacture, including a cord tying device for attaching monthly calendar pads to a back, a compartment for holding the monthly pads, an endless carrier positioned adjacent to said compartment, means for automatically feeding the monthly pads individually from said compartment into said carrier, means for holding the monthly pads stationary after leaving?,- said carrier, and means for automatically feeding the pad from its resting position to a position to be tied to the calendar back.

3. A pad feeding means adapted to be associated with a tying mechanism, including a compartment for a series of pads, means for ejecting the pads individually from said compartment means for carrying the pad away from said compartment to a resting position and means for automatically feeding the pad from the resting position to the tying mechanism.

4. In combination with a calendar pad tying mechanism, means for holding a series of calendar pads, an endless feeding means, a pad receiving and holding means, a feeding means associated with said pad receiving and holding means, said endless feeding means being disposed between said pad holding` means and said pad receiving means whereby the calendar pads are fed beneath the calendar back, from the pad holding means to the pad receiving means, and tied by said tying mechanism.

5. In combination with a calendar pad tying mechanism, means for holding a series of monthly calendar pads, a continuously operated pad feeding means and a pair of pad feeding` fingers, one operable to feed a pad into said continuously operating feeding means and the other adapted to feed a pad into the tying mechanism.

6. In combination with a calendar pad tying mechanism, a pad holding means, a continuously operating feeding means, a pad feeding linger associated with said pad holding means and a pad feeding finger associated with the delivery end of said pad feeding means, said pad feeding fingers operating in unison whereby when a pad is fed into said continuous feeding means a pad is automatically fed into said tying mechanism and said continuously operating feeding' mechanism is adapted to deliver a new pad into position to be received by said finger adapted to feed the same to the tying mechanism.
